Leadless pacemaker implantation in a patient with a fully magnetically levitated left ventricular assist device

Abstract

Left ventricular assist device (LVAD) therapy is increasingly used in patients with end‐stage heart failure. However, LVADs are associated with challenges, especially in the presence of a cardiac implantable electronic device. Although a leadless pacemaker (PM), the Micra™ Transcatheter Pacing System, can be used with LVADs, data regarding HeartMate 3™ LVAD are limited. In this report, we present a patient with a HeartMate 3™ LVAD who underwent successful leadless PM implantation after the removal of an infected cardiac resynchronization therapy defibrillator.

Single-chamber leadless endocardial pacing in last-generation centrifugal-flow left ventricle assist devices: a case report

“…Very few reports are currently available on patients with LVAD and LPMK 3,4 and both are mostly related to the same LVAD system manufacturer (HeartMate II and III; Abbott, North Chicago, Illinois, USA; Thoratec Inc.); in this regard, reporting and collecting data on this issue might be very important in light of the growing number of patients who could benefit from such a kind of therapeutic strategy. In this regard, the present case documents not only a hybrid levitation centrifugal pump (HVAD) but also highlights the tricks of concomitant implantation of LVAD and LPMK.…”

“…1 They can be the solution for left ventricle assist device (LVAD) recipients requiring pacemaker therapy, but some concerns remain on the potential interaction between the two devices. Some cases of adverse electromagnetic interference (EMI) between LVADs and implantable cardioverter defibrillators (ICDs) have been reported in terms of failure to establish telemetry or inappropriate shock delivery 2 ; on the other hand, only a few studies have described the interaction between LVADs and LPMKs 3,4 and both of these focus on HeartMate II and HeartMate III LVADs (Abbott; Thoratec Inc., Pleasanton, California, USA), highlighting the importance of gathering much more data on this specific issue among all the different manufacturers and models of LVADs.…”

Leadless pacemaker interrogation interference after conversion of a left ventricular assist device

“… 1 Successful leadless pacemaker implantations have been reported with no remote complications. 2 , 3 However, electromagnetic interference (EMI) in patients with LVAD between the programmer head and leadless pacemaker during implantations has also been reported, which could be solved by repositioning the leadless pacemaker. 4 Here, we report a case of EMI between the programmer head and the leadless pacemaker (Micra VR, Medtronic, MN) after conversion of the LVAD from HeartMate (HM) Ⅱ (Abbott, St. Paul, MN) to HM 3 (Abbott).…”

“…[1][2][3][4] Leadless pacemakers have been successfully implanted in patients with axial-flow Heartmate 2 and centrifugal-flow Heartmate 3 LVADs (Abbot, St. Paul, MN, USA) without evidence of EMI or device-to-device interaction. 5,6 Here we report a case of a Heartmate 3 LVAD and Micra VR transcatheter pacing system (TPS) (Medtronic, Minneapolis, Minnesota, USA) interaction requiring device repositioning.…”
